Abstract

A smoke internal circulation tail gas incinerator burner relates to a burner and comprises a burner shell, a brazier brick, a gas spray gun and a tail gas mixing adjusting mechanism, the brazier brick is fixed inside the front end of the burner shell, the gas spray gun is arranged at the center of the burner shell, and an ignition incandescent light is fixed on a flange at the rear end of the burner shell; the combustor shell is provided with four layers from outside to inside, the lower portion of the outermost shell is provided with a secondary air inlet, the upper portion of the second shell is provided with a tail gas inlet, the third shell is provided with a tail gas mixing channel communicated with the tail gas inlet, and the tail gas mixing channel is arranged on the upper portion of the third shell in an extending mode and located in the tail gas inlet. A primary air inlet is formed in the lower part of the shell on the innermost layer; the burner is high in ignition success rate, simple in structure, convenient to operate, complete in combustion and convenient to replace quick-wear parts.

Description

technical field [0001] The invention relates to a burner, in particular to a burner for a flue gas internal circulation tail gas incinerator suitable for a tail gas burning device. Background technique [0002] As is known, the burner of the tail gas incinerator is a carrier for the heat release of the tail gas incinerator. The sulfur-containing tail gas needs to be incinerated to oxidize the trace amount of H2S and other sulfides in the tail gas into sulfur dioxide; the tail gas incinerator is generally matched with the acid gas incinerator Use, as the combustion carrier of the residual H2S gas in the flue gas of the acid gas incinerator, it is required to burn the fuel gas through the burner to maintain the furnace temperature, so that the residual H2S gas is completely oxidized. The burner of the existing tail gas incinerator burns incompletely, the emission of NOx is not up to the standard, and the operating cost is relatively high. Contents of the invention [0003] ...
